Komekit remote access - iPad as Hub/DuckDNS

Hi everyone,

I have the latest home-assistant version installed with duckDNS and homekit configured.
I can access home-assistant outside my local network via HTTPS, however, I can only access homekit devices on my internal network, even though I have an iPad as Hub.

What could be the problem?
Here is my network config:

I also turned on homekit logs, but there are no warnings.

Thank you!

Found the problem.
I thought I had enabled this option, but I was wrong.
